商用节点临近 中国通讯业如何进行“5G超越”

2017-06-15 10:35:16   

2013年2月,IMT-2020(5G)推进组成立,中兴是成员单位之一。推进组的职责是梳理5G核心需求,甄别5G关键技术、研究5G可用频谱。自此,中国5G开始了有组织的推进。

根据最新披露的数据,截至2016年底,中兴累积的5G专利申请,已超过1500件。

“马拉松开跑后,要有坚定的配速目标,而不能乱跑。做5G,开始时要把握好方向,不能胡乱研究,要坚持让大部分用户能获得技术带来便利这个永恒不变的目标。”朱伏生说。

为此,中兴在2014年提出了Pre 5G的概念。

“Pre5G的核心思路,正是提前部署5G技术,让4G网络获得大幅度的性能提升,用户使用4G终端也能获得接近5G的体验。”朱伏生强调。

一方面,它令LTE网络实现了4至6倍的吞吐量增长,有效地解决了运营商在5G大规模商用前必须直面的两大问题:有限的频谱资源与MBB飞速发展的矛盾、人群密集场景下的容量提升和小区干扰问题。

另一方面,它兼顾了运营商的网络投资,在5G部署后,相关的设备和技术还能通过平滑升级继续沿用。

至今,中兴Pre5G已经在30个国家的超过40张网络中部署。

“Pre5G技术已经开始盈利。我们已经看到了价值,有信心在未来继续投资5G。”朱伏生自信地表示。

临近马拉松终点时,职业选手通常会及时冲刺,锁定胜局。

像中兴这样已经明显领先的选手,如果遇到了5G部署提前这样的变化,当然会增加获胜的几率。

2017年3月,3GPP第75次全会通过了5G加速的提案,按照加速后的新时间节点:非独立5G新空口标准将于2017年12月完成、2018年3月冻结。

此次加速有利于推动部分运营商在2019年即可实现5G新空口的大规模试验和部署。

在此之前,业界普遍认为2020年才是5G商用的时间节点。

因此,过去几年,各家巨头虽然在5G上各有落子,但大多按部就班、不温不火,虽然在各个技术领域持续推进,力求不失先手,但也在控制节奏,避免影响4G阶段的战果回收。

换句话说,5G 的蛋糕要抢,4G最后一口汤也得喝。战略布局的差距,往往就在这毫厘间。

对于还没有真正发力5G的选手来说,加速的消息太可怕了。你正准备超车,比赛结束了。

因此,对5G技术一向积极的中兴,必然成为形势变化的受益者。(记者 李雁争)
